`WAGON-BRAKE.

SPECIFICATION forming part of LettersPatent No. 227,215, dated May 4, 1880. Applicatlon filedv February 21, 1880.

To all whom 'it may concern Be it known that I, JAMES CARPENTER, of New Hope, in the county of Cayuga, in the State of New York, have invented new and useful Improvements in Wagon-Brakes (not patented' to me nor, with my knowledge or consent, in any f'oreign country,)and of which the following', taken in connection with the accompanying drawings, is a full, clear, and ex' act description.

In the accompanying drawings, Figure l is a side view of a vehicle provided with myimproved brake Fig. 2, an inverted plan view of same; Fig. 3, a front-end view; Fig. 4, an enlarged detail view of the devices by which power is transmitted to the brake-bar, and Fig. 5 an enlarged detail view of thebrake shoe and its connection with the brake-bar.

Similar letters of reference indicate corresponding parts.y

A represents the bra-kebar, arranged transversely underneath the body of the vehicle. To the front side of the brake-bar is bolteda block, B, and between the adjacentfaces of the brakebar and the block B is countersunk a nut, n, fitted into its seat, so as to prevent its turning and be completely inclosed therein, and thus be protected from dust and dirt.

Gis a rod passing transversely through the brake-bar A and 4block B, and having a screwthreaded part, a, workingin the nut n. From the threaded part a to the rearextremity, as shown at a', the rod is circumferentially diminished to allow it to freely pass through the of the said rod passes through nut and save the expense of cutting the threads the entire length of the rods. The rear end the hind bolster, e, ofthe vehicle, and is provided at opposite sides of said bolster with a nut, b, whereby it is adjustably restrained from longitudinal movement. By means of a set-screw, c, inserted through the side of the nut b and bearing on the rod C, the said nut is prevented from working loose. The opposite end of the rod C is inserted into the rear end of a tubular bar, D, and confined therein by a set-screw or pin, d, passing diametrically throughlboth bars.

.The bar or rod C is provided with a series of holes for the passage of said fastening-key, so as to admit of extending or contracting the length of the combined bars and adjust the same according to the extension or contraction of the reach. The tubular bar D is extended through the forward bolster', e', and to the forward extremity is attached a beveled gear, E, through the hub of which is inserted a key or set-screw, r, which passes through the tubular bar D and into a bolt, j', which is inserted into the interior of the front end ofthe tube and carries in front of the gear E a loose sleeve, g, which is provided on top with a socket, h, in which is stepped a vertical rod, F. The rod F is provided with a bevel-gear, E', which meshes into the gear E, and to the upper end of said rod is attached a hand-wheel orcrank for turning it. A set-screw, z', inserted through the side of the socket and entering a circumferential groove in the exterior oi' the stepped end of the rod F, prevents said rod from lifting out of the socket and maintains the two gears in connection with each other.

By the employment of the tubular section D, and its peculiar connection with the screwrod C and with the sleeve g, I obtain a light yet rigid means of transmitting power to the brake-bar, and adapt and greatly facilitate the attachment of the device to almost any vehicle.

The brake-bar A is terminated some distance inside of the wheels, and to its extremity is attached a springleat` or spring-bar, G, which projects over the periphery of the wheel.

H is a metallic brake-shoe provided with a socket orslot, s, by which it slides on the free end of the spring G. A set-screw, 7c, inserted through the back of the brake-slice and engaging the spring, serves to hold the brakeshoe in its desired position.

That side of the brake-shoe which faces the wheel is provided with a recess or socket, s', in which is inserted a wooden friction-block, secured therein by set-screws passing through the sides of the metallic shoe.

The object of employing the spring G in con nection with the brake-bar and brake-shoe in the manner described is to allow the shoe to yield to any variations which may exist in the bearings of the periphery of the wheel, and to allow the shoe to be set in or out7 so as to against the wheel different wearing-surfaces of the wooden friction-block, which may be of any desired width.

IOO

The ends of the brakebar slide and are supported on a bracket, @,011 the side of the vehicle-body. Plates u u, attached 'to the under side of the brake-bar and abutting against the inner edge of the respective brackets c fv, prevent lateral motion of the brake-bar and serve to maintain the brake-shoes in range with the wheels.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In combination with the holsters ce and the brake-bar A, provided with the nut a, the screw-rod C, having the circumerentially-reduced rear end, a', provided with nuts b b at opposite sides of the hind bolster, and the tubular bar D, adjustably connected to the for` ward end of the rod G by telescopic joint and by a pin or set-screw, d, and provided at its forward end with the gear E, substantially as described and shown.

2. rIhe combination of the tubular bar I), the gear E, applied to the end thereof, the boltf, sleeve g, provided with socket h, and the setscrew r, passing through the hub of the gear and through the bar D into the bolt f, substantially in the manner speciiied and shown.

3. In combination with the tubular bar D,

provided with the 'gear E, the bolt f, sleeve g, provided with the socket h and set-screw t', and the rod F, provided with gear E' and stepped in the socket h, and havin g on its stepped end a circumferential groove for the bearing of the set-screw, substantially as and for the purpose set forth.

4. In combination With the screw-rod C, the brake-bar A, provided with the block B, and the nut n, conned and inclosed between said brake-bar and its block B, substantially as and for the purpose specified.

In combination with the brake-bar A, provided at its ends with the sprii'lg-plate G, the shoe H, adapted to slide longitudinally on said plate and provided with the set-screw K, sub stantially as described and shown, for the purpose set Jforth.

In testimony whereof I have hereunto signed my name and aXed my seal, in the presence Y of two attesting witnesses, at Syracuse, in the county of Onondaga and State of New York, this 6th day of February, 1880.

JAMES CARPENTER.
